All Supercross SLT, PRO, and PRO LT Forks come with a welded in star nut and an Alloy Supercross Top Cap/Spacer stock that uses a 28mm open end wrench. Below you can purchase an alternative color top cap to change the look of your ride, or grab one of the new lighter Flush Top Caps which use a 6mm Allen Wrench rather than the large 28mm Open End Wrench. However you want to set up your fork we want to give you the options to do it the way you want.
